The Schedule rean-ed to inthe Letters Patent and making part of the lama.

To all whom it may concern Be it known vthat I, ROBERT A. MILLER, of the city of Boston, county of Snilk and State of Massachusetts, have invented a newl and useful Improvement on Boots and Shoes;y and I do hereby declal'e the following to be a full, clear, and exact description thereof, reference being had to the annexed drawing making a part of this specilication, in which- Figure l is a side view of my improved boot, with the last marked thereon in'full lines.

Figure 2 is the rear end of a right-hand last for the same, It is necessary for comfortable and easy walking t0 have heels of certain proportions put on our boot-s or shoes; also to have the curvature of the sole and the resting-place for the heel so arranged that the foot is easily kept inl its proper place.

'lhe latter requilements have too often been disregarded by common `manufacturers of boots and shoes,

and the results are the pressing forward of the foot toward the toes, soreness of the feet, and unsteady and uneasy walking, and the unequal wearing of the different parts of a boot or shoe.

To avoid theseevils Ihave made a boot of the following construction: l

I make the seatfor the heel of the foot horizontal', as shown at B C, fig. 1, whereby Iobtain a V steady supportfor the heel of aboutY two inches horizontal length. i

In combination with this horizontal plane I furthermore make the forward and under side-of this boot with a double spring, as shown by I), E, and F.

The curvature from Ev to F naturally keeps the foot from crowding too much forward toward the toes, and, in combination with the horizontal plane B C, keeps the foot in an easy and graceful position, thereby avoiding the enlargement of the big-toe joint; But to make this double spring e'ectual for theabovenamed pn1pose,I find it necessary to make the height of F f more than oie and one-half inch and up to three inches. y

Another complaint that also is very frequent with common boots and sh'oes is that no precaution is taken to prevent the foot from sliding sideways. Almost every person finds that he or she treads outward, that is, the foot will slide outward, whereby the counters are quickly worn and the disarrangement of the whole shoe will soon follow; besides, a painful ankle is too often the consequence. v lo avoid the latter complaints, -I make the deepest curvature for the heel'on one side of the center, as shown, G, iig. 2, and nearest to the inside of the boot, thereby obtaining a natural tendency for the foot to keep inward, and prevent the sliding out sideways of the foot .during walking.

Boots generally present an inclined plane from the heel to the toes, causinga strong pressure toward the toes', and also a sliding sideways of the foot.

Toavoid the abovenaxned objections is the purpose of 'my invention; and v What I claim is- The combination of the double spring D E F with the horizontal hollow seat B O, having the deepest part, G, between the middle and the inside of a boot or shoe, as fully set forth and described. f
